WINDING-DRUM.

Specification of Letters Patent.

Patented @013. 26, 1215.

Application filed February 24, 1914. Serial No. 820,528.

To all whom it may concern Be it known that I, LoUIs-PnLo UIN, a citizen of the United States, residing at Southbridge, in the county of Worcester and State of Massachusetts, have invented a new and useful Winding-Drum, of which the following is a specification.

This invention relates to a winding drum and connected parts, chiefly for use with a billiard chalk holder.

The principal objects of the invention are to provide an improved form of bracket for holding the drum and especially a simplification of the ordinary bracket used for that purpose; to provide rolls connected with said bracket in such way that the friction of the cord will be very materially reduced, and especially to provide improvements in the drum itself for the purpose of simplifying and cheapening the construction and permitting of the convenient and eX- peditions taking out and putting in of the central shaft and spring so that the latter may be repaired or adjusted. The invention also involves improvements in details of construction of thc'said drum and its connected parts.

Reference is to be had to the accompanying drawings in which,

Figure 1 is an end view of a billiard chalk holder and winding drum constructed in accordance with this invention; Fig. 2 is a front elevation of the same; Fig. 3 is a central sectional longitudinal view of the drum and the interior parts; and Fig. 4- is a plan of the blank for the drum extended out in a plane.

The invention is shown as involving a supporting bracket A, and a winding drum B for receiving a cord 0 for a chalk holder D. The bracket A comprises a plate 10 adapted to be secured to the ceiling or to the bottom of a billiard table and provided with two downwardly slanting legs 11 to which the drum is journaled, as will appear hereinafter. These parts are made. of a single piece of sheet metal and what I called a plate 10 consists of two of said pieces of metal bent around and brought into a plane. Between these two portions is formed a guide tongue 12 consisting of two straps of the metal bent down into parallelism with each other and integrally connected at the bottom. They are in plane parallel with the planes of the legs 11.

This tongue is made on a curve corresponding with the curve of the drum B, as will appear, and is provided with two antifriction rolls 13 which engage the cord C no matter whether it is pulled up or down.

The drum itself is made of a single sheet of metal, as indicated in Fig. 4. This sheet is composed of four parts. Two substantially rectangular parts, 14: and 15, and two substantially circular parts 16 and 17 constituting ends. The rectangular part It is provided with a slit at one end to form a tongue 18 which, when the parts are assembled, extends into a slot 19 in the circular end piece 17. At the inner end the part 14:, and at both ends the part 15, is provided with a semi-circular slit 20. These slits form cars 21 on the end pieces and these end pieces are also provided with additional ears 21 of the same shape. The rectangular part 15 is also provided with a key slot 22. The end piece 16 is provided with a slit to form a tongue 23 at a short distance from the center and both end pieces have circular perforations 2 1 and 25, re spectively, at their centers. In addition to this, the end piece 17 has 21. preferably circular perforation 26 considerably larger than the perforation 25. This part having been stamped out of sheet metal, it is bent up preferably by dies so as to form a substantially cylindrical drum, as indicated in the other figures. When this is done the two parts 16 and 17 constitute the circular ends of the cylinder while the two parts 14: and 15 constitute two spaced sections of a cylindrical surface between said ends. The ears 21, four of which are shown on each end piece, stick out beyond the cylindrical portion of the drum to guide the cord.

The drum is provided with a central shaft 30 having a small end 31 separated from the main portion of the shaft by a shoulder 32 near the end. This end 31 just fits the circular perforation 25 in one end of the drum. The perforation 24 in the other end of the drum is just enough larger to receive the opposite end of the shaft and constitute a bearing therefor. Fixed to one end of the shaft is a spring 33 having an opposite free end 3 1. The perforation 26 is large enough to permit the insertion of the shaft with the spring thereon.

The cord C is provided with a knot at the end which is slipped through the key hole bracket by means of screws 36 which extend into the ends of the shaft and hold the shaft in stationary position. IVhen it is I desired to remove the shaft to repair or adjust the spring, or for any other purpose, these screws are taken out and the drum removed from the bracket, then the shaft is pulled by the projecting end which extends through the perforation 24 until the opposite end of the shaftiswithin the drum and then thisis moved sidewise so as to make it extend out through the perforation 26. This end is then grasped and the shaft and the attached spring can be removed. In re-assembling these parts the large end of the shaft 30 and the free end of the spring 34 are introduced into the opening 26 and the parts manipulated by the other endof the shaft until the farther end of the shaft is caused to extend through the perforation 24, then the shaft is further manipulated to get the opposite end entirely within the drum and have it project out through the perforation 25. The objectof the inwardly projecting tongue 23 will now be seen. This serves as a ratchet tooth for the end 34: of the spring. If the drum is rotated in the wrong direction, this tooth easily passes over the free end of the spring onceduring each revolution. Nhen turned in the direction to windup the spring, this end necessarily catches under this tongue and holds that end of the spring so that, the shaft being held stationary and, the drum turned, the spring will be wound up and will cause the cord to wind up automatically on it whenever released after being pulled out. It will be seen, therefore, that the drum is supported and the cord guided by a very small sheetmetal bracket and the cord is prevented from having undue friction by the rolls no matter which way the cord is pulled out. Moreover, the drum is formed of a single sheet of metal and the spring and shaft are easily assembled therein and brought into operative conilitign without any nice adjustments of any Although I have illustrated and described only a single embodiment of the invention, I am aware of the fact that many modifications can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claims Therefore, I do not wish to be shaft in fixed position, a drum for receiving said shaft, said drum having a central perforation in each end fitting the ends of the shaft, a spring fixed to the shaft near one end and having a free end, the other end of said drum having means for engaging and holding the free end of the spring when the drum is rotated in one direction, and releasing it when rotated in the other direction, said means consisting of an inwardly extending tongue on the end of the drum.
